The 200 meter race times at a state track meet are normally distributed with a mean of 13.56 seconds and a standard deviation of
2.24 seconds. Using the standard normal probabilities table, what is the approximate probability that a runner chosen at random will have a 200 meter time less than 13.5 seconds? A. 0.4880
B. 0.6331
C. 0.7422
D. 0.5714
E. 0.7910
D.) The mathematical range is all real numbers greater than 0. The reasonable range is all whole numbers greater than 0 and less than or equal to 262,144.
